What is Born-Haber Cycle?
The Born-Haber cycle is an application of Hess's law used to calculate lattice energies of ionic compounds that cannot be measured directly. It is an energy cycle that relates the lattice energy of an ionic compound to other thermochemical quantities such as ionisation energy, electron affinity, atomisation energy, and enthalpy of formation.

Frequently Asked Questions
The Born-Haber cycle is an application of Hess's law used to calculate lattice energies of ionic compounds that cannot be measured directly. It is an energy cycle that relates the lattice energy of an ionic compound to other thermochemical quantities such as ionisation energy, electron affinity, atomisation energy, and enthalpy of formation.
Born-Haber cycles are used to determine lattice energies, to assess the thermodynamic feasibility of ionic compound formation, and to compare the relative stabilities of different ionic compounds. They are fundamental tools in inorganic and solid-state chemistry.
The thermochemical data used in Born-Haber cycles often involves highly reactive elements (alkali metals, halogens) and high-energy processes. Practical work with these materials requires appropriate PPE and controlled laboratory conditions.
The formula or notation for Born-Haber Cycle is: Lattice energy: U = −Mz₊z₋e²/(4πε₀r₀)(1−1/n); Born-Haber uses Hess's law cycle
